Actually, there's two DVC boards, this one and the rent/trade board. That's a logical separation. Here, everything DVC can be discussed regardless of resort. Actually if you look through the posts, I don't think there's that many resort specific posts. Mosts are about points, procedures, general questions on DVC etc.
Also, Robin didn't say, but I know it costs Pete a LOT of money to run this site, so adding more topic boards costs money out of his pocket, not ours. So, that said, this is probably a good opportunity to remind everyone that, thanks to Pete, this board is here. And IMHO, the best Disney board on the web !
